What is the ideal pH range for pool water?

The ideal pH range for pool water being 7.2 to 7.8 is crucial for maintaining a safe and comfortable swimming environment. This range is slightly above neutral (7.0), which helps to ensure the water is neither too acidic nor too alkaline. When the pH is maintained in this range, it reduces the risk of skin and eye irritation for swimmers, which often occurs if the pH drops below 7.2. Additionally, this range promotes optimal effectiveness of disinfectants, such as chlorine, ensuring that they work properly to keep the water clean and free of harmful microorganisms.

Maintaining pH within this ideal range also helps to prevent corrosion of pool equipment and surfaces, as well as the formation of scaling. Therefore, keeping the pH level within 7.2 to 7.8 is essential for both swimmer safety and the longevity of the pool and its components.
